Changelog * When invoked with the --auto-generate-sql option, mysqlslap dropped the schema specified with the --create-schema option at the end of the test run, which may have been unexpected by the user. mysqlslap no longer drops the schema, but has a new --create-and-drop-schema schema that both creates and drops a schema. (Bug #58090, Bug #11765157) * A new system variable, max_long_data_size, now controls the maximum size of parameter values that can be sent with the mysql_stmt_send_long_data() C API function. If not set at server startup, the default is the value of the max_allowed_packet system variable. This variable is deprecated. In MySQL 5.6, it is removed and the maximum parameter size is controlled by max_allowed_packet.

Bugs fixed:

* InnoDB Storage Engine: Replication: Trying to update a column, previously set to NULL, of an InnoDB table with no primary key caused replication to fail with Can't find record in 'table' on the slave. (Bug #11766865, Bug #60091) * InnoDB Storage Engine: The server could halt if InnoDB interpreted a very heavy I/O load for 15 minutes or more as an indication that the server was hung. This change fixes the logic that measures how long InnoDB threads were waiting, which formerly could produce false positives. (Bug #11877216, Bug #11755413, Bug #47183) * Replication: Using the --server-id option with mysqlbinlog could cause format description log events to be filtered out of the binary log, leaving mysqlbinlog unable to read the remainder of the log. Now such events are always read without regard to the value of this option.

As part of the the fix for this problem, mysqlbinlog now also reads rotate log events without regard to the value of --server-id. (Bug #11766427, Bug #59530) * Partitioning: A problem with a previous fix for poor performance of INSERT ON DUPLICATE KEY UPDATE statements on tables having many partitions caused the handler function for reading a row from a specific index to fail to store the ID of the partition last used. This caused some statements to fail with Can't find record errors. (Bug #59297, Bug #11766232) * InnoDB invoked some zlib functions without proper initialization. (Bug #11849231) * Two unused test files in storage/ndb/test/sql contained incorrect versions of the GNU Lesser General Public License. The files and the directory containing them have been removed. (Bug #11810224)

See also Bug #11810156. * Selecting from a view for which the definition included a HAVING clause failed with an error:

1356: View '...' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them

(Bug #60295, Bug #11829681) * The server permitted max_allowed_packet to be set lower than net_buffer_length, which does not make sense because max_allowed_packet is the upper limit on net_buffer_length values. Now a warning occurs and the value remains unchanged. (Bug #59959, Bug #11766769) * The server read one byte too many when trying to process an XML string lacking a closing quote (') or double quote (") character used as an argument for UpdateXML() or ExtractValue(). (Bug #59901, Bug #11766725)

See also Bug #44332, Bug #11752979. * Attempting to create a spatial index on a CHAR column longer than 31 bytes led to an assertion failure if the server was compiled with safemutex support. (Bug #59888, Bug #11766714) * Aggregation followed by a subquery could produce an incorrect result. (Bug #59839, Bug #11766675) * An incorrect character set pointer passed to my_strtoll10_mb2() caused an assertion to be raised. (Bug #59648, Bug #11766519) * A missing variable initialization for Item_func_set_user_var objects could cause an assertion to be raised. (Bug #59527, Bug #11766424) * mysqldump did not quote database names in ALTER DATABASE statements in its output, which could cause an error at reload time for database names containing a dash. (Bug #59398, Bug #11766310) * In Item_func_month::val_str(), a Valgrind warning for a too-late NULL value check was corrected. (Bug #59166, Bug #11766126) * In Item::get_date, a Valgrind warning for a missing NULL value check was corrected. (Bug #59164, Bug #11766124) * In extract_date_time(), a Valgrind warning for a missing end-of-string check was corrected. (Bug #59151, Bug #11766112) * In string context, the MIN() and MAX() functions did not take into account the unsignedness of a BIGINT UNSIGNED argument. (Bug #59132, Bug #11766094) * In Item_func::val_decimal, a Valgrind warning for a missing NULL value check was corrected. (Bug #59125, Bug #11766087) * In Item_func_str_to_date::val_str, a Valgrind warning for an uninitialized variable was corrected. (Bug #58154, Bug #11765216) * The code for PROCEDURE ANALYSE() had a missing DBUG_RETURN statement, which could cause a server crash in debug builds. (Bug #58140, Bug #11765202) * An assertion could be raised in Item_func_int_val::fix_num_length_and_dec() due to overflow for geometry functions. (Bug #57900, Bug #11764994) * An assertion could be raised if a statement that required a name lock on a table (for example, DROP TRIGGER) executed concurrently with an INFORMATION_SCHEMA query that also used the table. (Bug #56541, Bug #11763784) * For a client connected using SSL, the Ssl_cipher_list status variable was empty and did not show the possible cipher types. (Bug #52596, Bug #11760210) * With lower_case_table_names=2, resolution of objects qualified by database names could fail. (Bug #50924, Bug #11758687) * A potential invalid memory access discovered by Valgrind was fixed. (Bug #48053, Bug #11756169) * Bitmap functions used in one thread could change bitmaps used by other threads, causing an assertion to be raised. (Bug #43152, Bug #11752069) * SHOW EVENTS did not always show events from the correct database. (Bug #41907, Bug #11751148)

Just run the following commands to see what's happening, with the last two giving error?
